Each ICN is a volume with \(53\text{-by-}63\text{-by-}52\)  voxels, the sMRI volumes are resized to that same size using Scipy [1]}. The values in each volume are then rescaled to [-1, 1] by dividing the values in a volume by their maximum, which is also sometimes referred to as maximum absolute scaling. The dataloader and transformations were implemented with the help of TorchIO [2]}.
